Analyzer questions
What does ColdSEO's site analyzer check?
It runs 40+ checks across three categories: technical SEO (HTTPS, titles, meta descriptions, canonicals, robots/sitemap), Answer Engine Optimization (llms.txt, AGENTS.md, JSON-LD schema, FAQ structure, AI crawler permissions), and on-page quality (word count, heading hierarchy, internal/external links). You get a graded report with prioritized fix recommendations.
What is AEO and why does it matter in 2026?
AEO — Answer Engine Optimization — is the practice of structuring your site so AI search engines (ChatGPT, Perplexity, Claude, Google AI Overviews) can cite your content as the direct answer to a user's question. With over 30% of search now happening inside AI engines, AEO has become as important as classic SEO.
How is AEO different from SEO?
SEO optimizes for ten blue links — title tags, backlinks, page speed, keyword density. AEO optimizes for being cited as the answer — direct answer blocks after H1, question-style headings, FAQ schema, llms.txt, and explicit AI-crawler permissions. AEO sits on top of SEO; you need both.
What is llms.txt and do I need it?
llms.txt is a flat Markdown file at the root of your site that tells AI agents what your site is about, what your key pages are, and what facts they should treat as authoritative. It's the AI equivalent of robots.txt + sitemap.xml combined. Yes — you need one.
How does the verified directory work?
After running an audit, you can submit your site to the ColdSEO verified directory. We give you a unique verification file to upload to your site's root. Once we confirm the file is live, your site is listed publicly with its SEO scores, and you earn a permanent backlink from coldseo.com.
What is the verification file?
A small text file named coldseo-verify-[your-token].txt that proves you control the domain. You upload it to your site's root. We fetch it, confirm the token matches, and mark your listing verified — no DNS changes or admin access needed.
How do I improve my AEO score?
Start with the basics: add /llms.txt, /AGENTS.md, and /skill.md at your site root. Add a "Quick Answer" block right after every H1. Rewrite major H2/H3 as natural-language questions. Wire FAQPage JSON-LD that mirrors your on-page FAQ. Explicitly allow GPTBot and ClaudeBot in robots.txt.
Can this help me appear in ChatGPT or Perplexity results?
Yes — that's the whole point. AI engines pull citations from sites whose content is structured for direct-answer extraction. The AEO checks in this audit map directly to the signals those engines look for.
